Stainless steel parts
Stainless steel is widely used in industry for applications requiring high corrosion resistance or oxidation resistance at both room temperature or very high temperature.
The typical materials used for manufacturing stainless steel powder metal parts are as follows:
- Austenitic stainless steels. AISI 304L and 316L for high corrosion resistance, and 303L for easy machining. They are not ferromagnetic.
- Ferritic stainless steels. AISI 434L for high corrosion resistance. AISI 409L for high oxidation resistance at elevated temperature, and good weldability, and AISI 410L for machining before hardening. They are all magnetic, and their corrosion resistance is lower than that of austenitic stainless steels.
- Martensitic stainless steels. AISI 410 with heat treatment. Its hardness is very high, and it is magnetic, having a corrosion resistance lower than that of ferritic stainless steels.
The corrosion resistance of the sintering stainless steels depends strongly on the density and sintering conditions. As consequence, the correct way to design a stainless steel powder metal component is first to define a corrosion functional test for it, and to then design the manufacturing process in order to fulfil the test requirements.
Stainless steel is widely used as powder metal material in the following applications:
- Exhaust systems: Flanges, Hego-Boss sensor.
- EGR systems: Internal and external flanges, spacers, valve guides, gears, cams or rods for the valve actuation.
- Brakes: ABS sensor rings, rotor, stator and plates of vacuum pumps.
- Toothed parts: Special gears for electric motors, gearboxes, and other applications
- SCR pumps: G-rotors, gears and plates.
